With the GlockApps Inbox Insight tool, you can test emails via a single proxy email address and set up automatic email deliverability tests and monitor your message’s Inbox placement at the time interval you chose (every xx hours or xx days) without intervention.
You will see a deliverability report on your dashboard displaying where your email is placed in the mailbox. You can also receive alerts if your email doesn’t make it to the Inbox at any of the selected mailbox providers.
Before you can set up an automatic test or use a proxy test, you need to create a sending account where you enter the SMTP settings of your email service provider or delivery service that you are using to send your regular email campaigns. This is needed in order GlockApps can re-send the message to the seed list via your SMTP settings and imitate your normal sending.
How to Integrate GlockApps with Your ESP
In your account, go to Inbox Insight -> Sending Accounts.
Click “Create Sending Account.”
Type your sending accout name. It can be any name in order you can recognize the sending account in the dashboard.
Next, select the integration method.
To integrate with your Microsoft account (Outlook, Hotmail, or Office365), select “Outlook” and click “Continue with Microsoft”.
To integrate with your Gmail or Google Workspace account, select “Gmail” and click “Continue with Google”.
To enter the SMTP settings manually, choose “Custom SMTP” and complete the fields in the form:
From name – the name that will be associated with your email address.
From email – the email address your emails will be sent to the seed list from.
SMTP server – the name of the SMTP server.
Port – SMTP port number (465 or 587).
Security protocol – none or SSL. The “none” option works as STARTTLS.
SMTP username – login for your account with the SMTP server. As a rule, it’s the full From email address.
SMTP password – password for your account with the SMTP server. If your SMTP user doesn’t require authentication, type nopassword in the Password field. The username can be any or empty. With nopassword, the username is ignored.

Next, you can optionally configure the Header Settings and Proxy Settings.
In the Header Settings, you can speficy which email headers to keep and/or which custom headers to add when re-sending your email to the seed list.
In the Proxy Settings, you choose the inbox providers and generate a proxy email address to be used for proxy tests.
When done, click “Continue with Custom SMTP”.
If your SMTP settings and login credentials are correct, the sending account will be successfully saved.
If something is blocking the connection to the SMTP server, an error message will be returned. Read the error description and correct the entered settings.
